Comment 9 for bug 1473047

Wojciech, sorry for delay.

It's proposed here: https://review.openstack.org/115340 to share networks between node groups. So, some networks in group A and group B can be shared (like Storage) and other ones are not (like others in your description).

It will look like just one network E is being used in both node groups not E1 + E2.

Thus, if all the nodes from particular node groups have the same requirements for networks it should work. Actually, it is supposed that nodes are distributed among node groups on the base of network requirements. So, if nodes have different network requirements they should be in different node groups. Does this work for you?
